Specification of Letters Patent No. 12,626, dated. April 3, 1855.

Be it known that I, SMITHG O i/L; of Troy, in the county of Rensselaer, Stateof New York, have invented. a new Mode for Figure l is a descriptlon of the coupling C, is the female part in which the clutches which secure the: male and female Fig. 2 is the one half View of 1 h, h, is the ring which secures the spring clutches. j

Fig. 8 shows an end View of the packing. Having thus fully described the nature of my invention what I claim therein as new and desire to secure by Letters Patent is-. A hose coupling composed of two partson one of which are spring clamps or jaws controlled by a friction ring, and on the. other a groove into which said jaws or clamps take, the whole being so arranged when united, as to make a tight joint, and

yet allow one half of the couplingto turn on theo-ther halfwithout uncoupling it, as set forth. 7
